• What is the cause and solution for SAP error message CNV_10020567 - Transaction CNV_10020_MEMTMON shows memory requirements per table ?

  The SAP error message CNV_10020567, which is related to the transaction CNV_10020_MEMTMON, typically indicates that there are memory requirements for specific tables during a data migration or conversion process. This error is part of the SAP Data Migration Cockpit or the SAP S/4HANA migration process, where large volumes of data are being processed.
  Cause:
  The error is generally caused by insufficient memory allocation for the data migration process. When migrating large tables, the system may require more memory than is currently allocated, leading to performance issues or failures in processing.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Increase Memory Allocation:
  
  Adjust the memory settings in your SAP system. This can be done by modifying the instance profile parameters, such as abap/heap_area_dia and abap/heap_area_nondia, to allocate more memory for dialog and non-dialog processes.
  
  
  
  Optimize Data Migration:
  
  Review the data being migrated and consider filtering out unnecessary data or breaking the migration into smaller batches. This can help reduce the memory load during the migration process.
  
  
  
  Monitor Memory Usage:
  
  Use transaction ST02 (Tune Summary) to monitor memory usage and identify any bottlenecks. This can help you understand if the memory settings are adequate or if further adjustments are needed.
  
  
  
  Check for Locks:
  
  Ensure that there are no locks on the tables being migrated that could be causing delays or memory issues. Use transaction SM12 to check for and resolve any locks.
  
  
  
  Consult SAP Notes:
  
  Look for relevant SAP Notes that may provide additional guidance or patches related to this error. SAP frequently updates its knowledge base with solutions for known issues.
  
  
  
  System Resources:
  
  Ensure that the underlying hardware resources (CPU, RAM, etc.) are sufficient for the migration workload. If necessary, consider upgrading the hardware.
